Annapolis Junction Lot 6

TCA Tilt-Up Project Profile - Innovative Application/Technology Division

Article tools: Coming soon!

Believed to be the first of its kind, Annapolis Junction Lot 6 meets the blast requirements of DOD ATFP Medium level security while using conventional tilt-up construction techniques and no additional structural steel at the perimeter.

The project team successfully worked to find a solution that allowed the roof structure to be built using bar joists after realizing joist manufacturers were unable to meet the specified blast criteria. The project's architectural features include: curtain wall, aluminum sunshades, a two-story lobby with clerestory, aluminum canopies at the entrance, form liner, textured paint and rain-screen metal panels.

The project has achieved a LEED Gold Certification.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
